application filed August 20, 1913. Serial No. 7815,6429.

To all whom it may concern:

Be it known that I, J OHN Knosr, a citizen of the United States, residing at New York, in the county of New York and State of New York, have invented new and useful Improvements in Embroidery-Machines, of which the following is a specification.

My invention relates to embroidery machines and its object is to provide in ma chines of this character mechanism Whereby a cord, braid, piping chenille, threaded beads or other ornamental threads may be sewed to the material to be embroidered. The material is not passed through the me but is stitched on the surface of the in. lo by means of the needles, which in case of being a braid will sew through the center of same and in case of being a cord the needle will operate first on one side then on the other in a Zig-zag manner.

A further object of my invention is to provide means whereby the cord or other ornamental threads may be formed into any predetermined design or pattern and held in this position until sewed onto the fabric by linotner object of the invention is to provide means whereby the cord. or ornamental thread may be formed into a complete cirole, without said cord or thread being twisted around the needle,'and thereby preventing its breaking.

Still another object of the invention 1s to provide automatic means whereby the cord or ornamental threads are automate call untwist'ed, relative to the needle whether the direction of the pattern runs from left to right or vice versa.

T invention further consists of parts and. ambinations of parts all more fully disclosed hereinafter and particularly pointed out in the claims.

I Reference is to be had to the accompanydrawings, forming part of this specifics which similar characters of reference corresponding parts in all the views vhichz e 1 is a front elevation of an em- T machine embodying my invention. i. 2- 1S a detached view of th left hand side ofthe machine, showing th tape actu ating and cord guiding device, also the tension controlling mechanism.

Fig. 20 is a detached side ole-- vation of the adjustable cord holder. Figs. 21-22-23-'24 are vertical cross-sections of the presser-foot and guides, showing pro-. gressive steps in attaching the cord to the fabric. Fig. 25 is a view of a pattern to be embroidered. Fig. 26 is a series of diagrams, showing the progressive steps used in embroider-lug the pattern shown in Fig. 25. Fig. 27 is a diagrammatic view of the embroidery machine, showing to a better advantage its connections and automatic reversing mechanism, and Fig. 28 is another diagram of the machine showing a manually operated reversing device.

To the lower part ofthe free end of the pantograph 80 is attached the usual pointer 31 which serves as a guide to trace the pattern on the pattern board. This pointer is mounted to revolve in bearing 32 of said arm and held in position by a collar 33 on the inside of the arm, and a bevel gear 34 on the outside. To this collar 33 is fastened a guide 33 which has an outward extended portion ,33" adjacent to the pattern board, the object of this is to be explained later. Adjacent to the pointer 31 is the ordinary spacer or rest 31*. At the l'owengaid of arm 30 is the/ ordinary handle 30 'w i-iereby the pantograph 30 is moved. The bevel gear 34 fastened to the outer end of the pointer meshes into another bevel gear 35 which is fastened to the handle 36 and is revolubly mounted on the lower end of arm 30. Another bevel gear 37 meshes into gear 34 and is fastened to a short shaft 38 supported in a bearing 39. On the other end of said bearing a bevel gear i0 is secured to shaft 38 which meshes into a bevel gear 41 secured to shaft 42, mounted to revolve in bearings 4343, fastened to arm 30. At the upper end of said shaft is a bevel gear 491 fastened thereto, and meshes into a gear 45 which is loosely mounted on a stud 16 which also serves as a connection of the pantograph. Integral with gear 45 is a sprocket wheel 47. This is best shown in Figs. 910. The object of the arrangement shown in Fig. 9 is to allow an unobstructed view of the pattern on the pattern board C.

Fastened to the frame A of the embroidery machine is.the usual support 48 for the pantograph 30. Through the upper connection thereof passes a small shaft 19 which extends outward and serves as a trunnion for a sprocket wheel 50, which connects with sprocket wheel 47'by a chain 51. Integral with sprocket wheel 50 is another sprocket wheel 52 which connects with sprocket wheel 53 by a chain 54 to the tension controlling device, its purpose to be explained later. Integral with wheels 5052 is a gear wheel 55which meshes into a small gear 56, mounted to revolve on a stud 57, fastened to bracket 48. Integral with this small gear 56 is a large disk 58 with a serrated edge. Below this disk 58 is mounted'a lever 59, fulcrumed at 60, on the standard 48. This lever 59 has at its upper end a spring pressed dog 61 which is always in engagement with the serrations of the disk 58. If the disk revolves in the direc-. tion of the arrow this dog will simply slip over the serrations, but in case of a reverse movement will take hold of the serrations and cause the lever 59 to reverse its position, shown best in Fig. 12. To the lower end of lever 59 is connected a rod 62 which connects to the upper end of lever 63, fulcrumed at 64 on a bearing 65, extended from the frame A. The lower end of this lever is connected to a clutch member 66 which slides on a feather 67 on the drive shaft 68 of the machine proper. This shaft is driven from the usual counter shaft 69 well known in the art.

On the drive shaft 68 are loosely mounted two bevl gears 70-71', these gears have at theirinrer sides, teeth 7 0 -71, which register with teeth 66 of the sliding member 66. Meshin into these gears 7071 is another gear 72 which is fastened to a shaft 73, mounted to revolve in suitable bearings 74 supported from the frame A. At the upper sprocketaoeaars When the tension on the spring 82 is properly adjusted, more or less friction may be had, between gear 76 and disk '79.

It will now be seen, by referring to Fig. 1, that when-the operator turns the handle 36 of the pantograph in one direction of the delineated design on the pattern board, the guide 33* following the pattern or direction of the line as closely possible, the motion will be transmitted through the several gears and chains to shaft 106, it will also cause the small gear wheel 56 to re volve disk 58 and thereby actuate the lever 59 as before described. The ob ject of having the disk 58 large is that a slight reverse movement of handle 36 will cause the reversal of lever 59. \Vhen said lever is moved into dotted. position shown in Fig. 12 it will cause clutch member 66 to disengage from gear 71 and engage the clutch on gear 70, thereby reversing the motion of shaft 73 and its connections. It will therefore-be seen, that shaft 73 runs continually either in one direction or the other and that the motion to shaft 77 is transmitted through the friction drive B. By referring to Fig. 27 it will be seen that shaft 77 runs the whole length of the machine and is supported at intervals by suitable bearings 84.

At each end of the machine close to the inside of frame A are located transverse shafts 86, mounted to revolve in suitable bearings 87. These shafts'are connected with shaft 77 with pairs of bevel gears 87=-88 so as to run in opposite directions. At'the forward ends of these shafts are fastened cams 8990 which coiiperate with rollers .91, fastened to slide in members 92-93, mounted to slide horizontally in brackets 94-95 fastened in suitable manner to frame A. On shaft 85 back of bracket 94 is fas'tened a .mutilated gear 96 meshin into another gear 97 which is fastened to a shaft 98 which revolves in suitable bearings 99, of the bracket 94, just above shaft85. On shaft 98 is also fastened a worm-wheel 100, which meshes witlra worm 101. This worm is fastened to a transverse shaft, 102 and is supported by brackets 103 extended upward from bracket 94:. At the outer end of sl.;.ft '10/2 is fastene'd a bevel gear 104:, which meshes into another gear 105 on a. horizontal shaft- 106 which is supported from breaka e and mounted to revolve 'in'suitablejbearings 107.

weenie 3 At the forward end of this shaft is fastened a sprocket wheel 53. Just below shafts 8586 and in line with the lower row of needles are mounted short shafts 108109, 53. these shafts are mounted in suitable brackets 110-111 fastened to frame A. To the inner ends of these shafts are fastened sprocket wheels 112 and are driven from shafts 85-86 through chains et-105 from m sprocket wheels 106-407 secured to shafts 85-86. On the outer end of shafts 108 109 are fastened cams 108'---l09. The sliding members 92-93 fits into a dovetail grooi e of bracket 94 and is moved back and forward by cams 8990. The

sliding members 92-93 extend inward toward the center of the machine and carries adjustable cross-bars 114: l15. The outer ends of these bars are connected together by 2a a rod 116 and held tight by a screw and thumbnut 117. This rod 116 has loosely mounted rollers 118 which serve as guides for the cords 119 to the needles 120. The inner ends of cross-bars 11 111-5 are conne'cted together with a perforated steel tape 121 which revolves the cord guides 122 and will described later. It will be understood that there are two sets of these frame like structures, formed by the cross-bars 114; 115, the rod 116 and the perforated tape 121, one in front of each row of needles. The cord guides 122 are made very thin in of ring with recesses 123 on eachitting into holes or bearings 12 1 in the -r foot 125 and are held in position by Wei- 1128 fastened. thereto by screws 129.

cord guides 122 have at their periphery s or 126 meshing into holes 12? of l tape 121. The cord guides 122 have a .mali annular groove 130 at the inside, into un "a fits a ring 131, and is held fromturn- *ictional engagement. This ring is with diii'erent sized eyes 182 i which the different sized cords are No. 'i'fhe object of this ring is to get an adjustment of the cord, also to leave much room as possible around the needle as not to obstruct the view of the stitch.

" perforated steel tape 121 is passed over cord guides 122 into the box like strucof the presser foot 125, so it will mesh .1 ah the teeth 126, then it is passed under a r-nall idler 133, then over another cord 'ui'ieand so on. The object of the idler is to give the tape a larger bearing on the cord guide. The usual apertures for the borers are shown at 134-. The presser foot is fastened and driven by the machine in the usual manner. It will be seen that the driving or oscillating mechanism for the cord guides is completely covered up, thereby preventing dust and lint making 1t inoperative.

From the foregoing it will be seen, that,

55 as the shaft 73 is drivencontinually in one or the other direction, according to the retation of the handle 36 of the pantograph 30, it transmits its motion to the friction disk B, and'as the shaft 77 is locked from rotation by the worm 101 and worm gear 100 will cause the friction disk to slip, until the mutiliated gears 96-97 are out of mesh, the shaft 77 will then be free to make one half revolution, this of course will turn shafts 8586 as well as 108 409, thereby throwthe needle 120.

Referring to Figs. 7 and 15 it will be seen that the cord spools 135 are mounted to turn on standards 136 and the cord 119 is passed over pulley 118, thence into 'the eyes 182 of the cord guide 122. The threading of the needle is done in the usual way, the shuttlebar 137 is also of the usual construction.

Referring to Figs. 21--2223 and 24 it will be seen that in starting the embroidery, the cord 119 is first passed through the eye on top, then back of the cord guide 122 and downward then outward through the lower eye 132. The machine is now ready to start and the needle will. sew the cord to the fabric, owing to the fact that the cord comes right in front of the needle. In using a round cord the needle isguidcd from one side to the other, as it would be impossible to strike the center, therefore a round cord would be sewn 0n the fabric, practically with invisible stitches. 4

Assuming that-a pattern like Fig. 25is to be embroidered, the operation will be as follows :Starting at a and working in the direction of the arrow, the cord 119 is at the top of the cord guide as shown at 138 in Fig. 26. The cord guide 122 is turned to the right untilthe cord 119 is at the bottom as shown at 139. It will now be seen that the cord 119 is half way twisted around the needle 120, at the next movement, or in other words, as the operator continues to turn the handle 86 in the same direction, the mutilated gears will get out of mesh and cause the cord guides 122 to be rotated one half revolution in the opposite direction, bringing the cord 119 untwisl'ed as shown at 1 10. As the operator continues to rotate in the same direction the cord carriers 122 also turn in the same direction as before until the top of the pattern -is reached at b,
